“They’ve just started work on Season 3, and Chris is at odds with Lena,” the source said. “He didn’t like the direction things are going in, which seems a bit odd since the show put him on the map.”

In a statement released on Thursday, Chris’ rep said, “[Chris] is grateful for the experience of collaborating with Lena, Judd [Apatow], and the entire ‘Girls’ cast and crew, but right now he’s working on numerous other projects and has decided not to return to the show.”
